What 30140 covers
An otolaryngologist uses a submucosal approach to reduce enlarged inferior turbinate tissue while preserving the overlying mucosal lining. The procedure is commonly performed for persistent nasal obstruction associated with inferior turbinate hypertrophy, including when symptoms remain despite medical treatment. It may be done in a hospital outpatient department, ambulatory surgery center, or an appropriately equipped office setting.
Select 30140 for the submucosal reduction, not removal of turbinate tissue by excision. The operative report should identify the inferior turbinate, the submucosal approach, and whether one or both sides were treated. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral treatment, modifier 50 is paid at 150%. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
